Like letters'ofreference reifer-to like parts in i the several figures A is the snnken'v'esselto 'be raised,jand B ,B,fa're two` parallel wrecking vessels or floats which areanchore'd adjacent to each other i directly over-the wreck.

The, guide pulleys are attached. to anchors I, dropped' ashort distance beyond the wrecked vessel jand on opposite sides of the same.

the ends of each lifting loop being connected with the piston rods of two such jacks located `npon the two Wrecking Vessels, respectively. Each of the lifting jacks operates in conj unction with two cable grips or clutchea'as shown in Fig. 4.

isI a spring whereby the wedges are caused to bear against the cable with suilicient force to be drawn into the tapering block by the cable. internally screw This spring is arranged in an threaded socket, lo, formed in the rear side of the sliding block and isy compressed between a washer 703, bearing against the adjacent ends of the wedges and a washer 7c, bearing against an adjusting collar or sleeve 7c, which engages in the inter. n ally threaded socket k2. 'lhis'ad j usting collar enables the tension of the spring 7c', to be properly regulated. During the outward or return stroke' of the piston rod, the wedges are loosened, permitting the clutch to ladvance on the cable the same.

7e is a spring interposed between the small ends of the wedges and a shoulder k7 formed at the smallend of the tapering opening Yof the blocks` Thisl spring is compressed wheny the wedges are forced into the opening of the block and-assists by its reaction in releasing the wedges and also serves to retain the wedges in their proper relative position'.

lhe stationary or detent clutch K vis constructedV in all respects like the draft clutch just described, except that the block which receives the wedges, instead of being movable,'is secured to a stationary part of the vessel in front of the movable clutch. During the advancing stroke of thedraft clutch K, the wedges of the detent clutch release'their hold upon the cable,- allowing the same to be hauled in by the draft clutch, but during the return stroke of the latter, the wedges of the detent clutch grasp the cable and prevent its slipping back. The lifting loop connected with the jacks is thus gradually hauled up, by the reciprocating movement of the pistons of the jacks.

While I prefer to employ the clutches herein shown and placed by clutches of any other suitable con- Under each lifting jack a drum or reel M is preferably arranged, upon which drums the slack of the lifting cables is wound, these cables running from the rear side ofthe draft by the piston4 rod from for taking a new hold on described, they `may be reclutches downward through openingsin the deck and thence to the drums'.

In raising a sunken vessel by my improved apparatus, a cable of sufficient length to form one of the lifting loops is attached at one endto the free ends of' the auxiliary hoisting cable, and draft cable carried by one of the wrecking vessels.l This lifting cable is then carried' around one end of the wreck in the form of a loop, by a tug or other craft, and its opposite end is attached to the free ends of the auxiliary'hosting cable and -draft cable carried-bythe othervfwrecking vessel, after which the lifting loop and the draft and hoisting cables connected thereto are allowed to sink to the bottom of the sea as shown by the horizontal loop in Fig. l. The lifting loop thus lowered is next drawn under the wreck by hauling in the draft cables, ends of the lifting loop are pulled forward, dragging the loop under the wreck. The

branches of the loop are now raised to a perpendicular position by means of the auxiliary hoisting cables, ing loops in Figure l, and after the loop has been raised its ends 'are detached from the hoisting cables and one ot such ends is attached to the clutches of a hydraulic jack of one of the wrecking vessels and the other end whereby the as ,indicated by the depend,

tothe'clutches of an opposite hydraulic jack i t onthe other wrecking vessel.

For the sake of elearness, a single loop is referred to in the above description, but the loops are preferably arranged in pairs,-as

shown in Fig. l, and the ends of one loop of each pair are connected with opposite hydraulicjacks located on the outer sides of both wrecking vessels, and the ends of the other loop of the samopalr are connected with opf posing hydraulic jacks arranged on the inner sides of the wrecking vessels. By this arrangement, the strains exerted by the loops ofl each pair is equalized on both -sides of the wrecking vessels, preventing undue careening or capsizing of the same.

f After the first pair of lifting loops has been adjusted and connect/ed with the hydraulic jacks, additional loops'are successively lowered around the wreck, and drawn under the same to the proper point, raised to a perpendicular position and attached to the series of hydraulic jacks upon the wrecking vessels, in the manner described, with reference to the first pairof loops, the hoisting and draft cables being detached from each pair of loops, preparatory to connecting the loops to the hydraulic jacks and being then attached to the until all the loops have been ad? justedand connected with their respective jacks, as many pairs of hydraulic jacks be# ingl provided upon the wrecking vessels as there are loops. loops have been connected with"the hydraulic jacks the latter are set in operation, whereby allof the loops are simultaneously hauled up and the wrecked vessel is raised. Each pair of lifting loops is preferablyhauled up a short After the various lifting y ce after being kadj ustedjaround `4the 4'sunk n vessel,gso as to raisethe latter' slightly and 'permit the succeeding. lifting loops to 'be drawn under the same-more easily.- j' ln order to facilitate the hoisting of the 'v rious lifting loops and avoid entanglement; o'f

The various jacksfmay be connected by 3 5 pipeswith an'accumulator or acommon pressuretank and a Valve controlling--- all of the jacks may be arranged in the vmain pressure supply pipe, and an independent valve may bearranged in the branch pipe 'leading to 4o each jackto enableeach jack to be operated i ,independently of the rest, if desired.- r i 4In raising a vessel snnk'npon a sandy bot-ff ftom, the apparatushereinbefore described is 'suicienna's-the sand permits the lifting loops 4510 be drawn under the Wreck, but in lraising a vesselsunk on rocks, it is necessary to raise the'vessel at one end sufficiently to -draw the lifting loops'under'thesame.' For this pur-`- pose, the .'appa'ratus'- shown inliig. 5. may be 5o employed. This consists of an upright lift v ing loop Oipassing'around the oyerhanging stern of the sunkenvessel and connected at its lo p isheldat the properangle toprevent its slxrping oEthe-stern.= This retaining loop is provided/at its-endsf-with rings p, through, 6o lwhich the branches ,Lof the lifting loop pass loosely.
